Hi,Do we have members that have used or own a Rheninghaus meat slicer. I am going to inspect a secondhand smaller model that came from a small restaurant, now closed. It looks in a good clean condition but according to the lady owner it has a low rumbling noise when cutting. ( motor bearings may be?) It comes complete with the top mounted sharpening stones.At first I thought it was a German made slicer but it is actually made in Italy.Any advise greatly appreciated.Thank you,Jan.
